Tacrolimus-Induced Neurotoxicity After Transplant: A Literature Review

Area of Science:

• Pharmacology
• Neuroscience
• Transplantation Medicine

Background:

• Tacrolimus is a vital immunosuppressant for preventing organ transplant rejection.
• Tacrolimus use is linked to significant nephrotoxicity and neurotoxicity, even at therapeutic doses.
• Tacrolimus-induced neurotoxicity presents diverse symptoms, posing clinical challenges.

Purpose of the Study:

• To review and compile pharmacologic management strategies for tacrolimus-induced neurotoxicity.
• To identify potential interventions for preventing and treating neurotoxic adverse events associated with tacrolimus.
• To guide future research into the pathophysiology and patient-specific mitigation of tacrolimus neurotoxicity.

Main Methods:

• Analysis of 28 case reports of tacrolimus-induced neurotoxicity.
• Inclusion of literature including reviews, retrospective studies, and animal models.
• Synthesis of findings with clinical experience to propose management options.

Main Results:

• Tacrolimus-induced neurotoxicity ranges from mild symptoms to severe conditions like PRES and CIDP.
• Management strategies were compiled based on case reports and clinical experience.
• No established guidelines currently exist for treating tacrolimus-induced neurotoxicity.

Conclusions:

• Effective management of tacrolimus neurotoxicity is crucial but lacks standardized guidelines.
• Further research is needed to understand tacrolimus neurotoxicity's pathophysiology.
• Developing patient-specific strategies is essential to balance neurotoxicity mitigation with rejection risk.
